Spanish technology tree
The Spanish technology tree index links recorded Age of Empires III units, buildings and research to their individual reference pages. It emphasizes entries whose game data directly identifies this faction and is not a complete reconstruction of every shared option in the in-game tree; check unit and technology pages for additional civilization access.

Civilization roster and research
The lists are grouped into units, buildings and technologies, then organized by the Age recorded in the game data. Shared options can appear in more than one civilization index; inclusion does not mean an item is unique. Follow an entry to check its cost, production or research site, prerequisites, counters and version band. A Home City Card, map alliance or scenario rule may change access, so this list is not a fixed build order.
Scope and availability
Scope: Age of Empires III civilization content. This index reflects matching entries in the saved game-fact records; each linked page gives its own version, Age and access conditions.
How to read the tree
Use the tree when planning an Age-up, Home City deck or response to an opponent. Find the unit line or upgrade that answers the immediate matchup, then check its entry for exact values and access rules. Map, mode, shipments, patch and edition determine which recorded options are useful in a particular match.

Check the entry for version and prerequisites
An index can include options recorded across multiple Age of Empires III releases. Older faction names, card unlocks, research prerequisites and campaign-only rules can change availability. Check the linked page’s version band and conditions before applying an option to a specific game.
Faster Home City shipments influence the timing
The Spanish need less Experience than other base-game civilizations to earn Home City shipments. Treasure hunting, combat and Trading Posts can therefore advance the next card sooner, making the deck an important part of how the listed roster reaches the field. This is a shipment-cycle advantage, not a change to unit costs or research requirements. Read the age-grouped list alongside the Home City Card entries to see what arrives immediately and what still requires ordinary production.
Combine fast melee troops with ranged support
Rodeleros and Lancers give the Spanish distinct melee options: Rodeleros can pressure vulnerable targets, while Lancers bring heavy cavalry damage. They still need support against their counters, so do not read the tree as a single-unit build order. Use shipment timing to fill an immediate gap, protect cavalry from anti-cavalry troops, and add infantry or artillery for targets that a mounted force cannot safely handle. Confirm each unit’s actual Age and access on its entry, especially when comparing older guides with Definitive Edition rules.
